This will be a newbie question, so please bear with me...
I have a MySQL database with a test schema in. I can read and write to it using node red. So far so good.
I gather that to get the information in to a chart I have to use the 'change' function.
However, I just can't wrap my head around how to make it work. I have zero background in JS. Would anyway one able to point me in the right direction?
My test schema uses id (int) Value (real) and Timestamp (DT)
My test query brings back just the value and the timestamp, as that is all I want at the moment
Any assistance would be much appreciated
